BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc player for reproducing a disc on which music information and the like is recorded, and more particularly, to a disc player capable of miniaturization, compactness and light weight.

Recently, as a disc player, for example, as disclosed in Japanese Patent Laid-Open No. 63-206951, a magazine loaded with a plurality of discs is inserted into a chassis, and a disc selected from this magazine is placed in the player body. There is one that can be loaded and played.

The loading device that selects and loads a single disc from the magazine containing a plurality of discs and loads it into the player body includes an elevator mechanism for positioning the selected disc at a predetermined height relative to the player body, and the disc at the height from the magazine to the player body. A slide mechanism for moving is provided.

Each disc is individually mounted on a disc mounting plate, and the slide mechanism moves the slide mounting plate horizontally to position the disc receiving portion of the disc between the spindle table of the player body and the clampers facing the lower side thereof. Then, the clamper is lifted so that the disk storage portion of the disk is held by the spindle table and the clamper, which causes the disk to float from the disk mounting plate so that the disk can rotate without contacting the disk mounting plate.

As a method of horizontally moving the disk and the disk mounting plate, a method of linearly moving in a direction parallel to the end edge of the disk mounting plate, and turning about the corner of the disk mounting plate as disclosed in the above publication, Although there is a method, the disc housed in the magazine is loaded in the player body by horizontally moving the distance beyond the diameter.

For this reason, in the conventional disc player of this kind, it is necessary to set at least the dimension of the disc moving direction at least twice the diameter of the disc, which is disadvantageous in miniaturization, compactness and weight reduction.

In particular, in the method of turning around a corner of the disk mounting plate as in the above publication, the moving space of the disk mounting plate becomes larger, which further disadvantages the miniaturization, compactness, and light weight.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a compact, compact and lightweight disc player.

The disc player of the present invention includes a chassis provided with an opening on one side of the front face, a player body disposed on the other side of the chassis and having a spindle table and a clamper opposed thereto, a disc mounting plate for mounting discs one by one, and a plurality of discs. A magazine in which the disc mounting plate of the disc is separately retractable, the magazine being releasably loaded through the opening in the chassis such that the outer peripheral edge of the disc is in close proximity between the spindle table in the player body and the clamper opposite thereto. And an elevator mechanism for aligning the up-and-down position of the selected disk with the spindle table of the player main body and the clamper opposite thereto, and the disk mounting plate on which the selected disk is mounted; And a clam opposite to this It is characterized by including the slide mechanism which sets a disk accommodating part between furs.

According to the present invention, since the magazine enters and exits at a position close to the peripheral table of the disc loaded in the magazine between the spindle table of the player body and the clamper opposite thereto, the disc loaded in the magazine has a disc storage portion at its radius. By moving the distance slightly larger than the dimension plus the radius, the disc housing portion can be positioned between the spindle table of the player main body and the clamper opposite thereto, and compared with the conventional example, the disc width of the disc player is increased. It can be miniaturized by shortening the width.

Further, in the disc player of the present invention, the disc mounting plate has a semicircular cut out portion of the disc loaded into the player body, and the magazine has a lower surface of the ceiling plate located above the disc carried into the player body. This semicircle is thinly formed.

Thereby, even if the vertical space | interval of a disc mounting plate is set small, it is prevented that the disc conveyed in the player main body can contact the lower surface of an upper disc mounting plate or a magazine ceiling wall.

Further, in the disc player of the present invention, the disc mounting plate has an up and down motion regulating convex portion in contact with the surface of the lower disc, and at least one of the convex portions is located below the disc mounting plate when the disc mounting plate is completely moved toward the player body. It is formed in the position which contacts the surface of a lower disk.

As a result, the disc in the magazine is controlled up and down by the disc mounting plate at the top thereof, and at the same time, even if the disc mounting plate is completely moved toward the player main body and some of the convex portions are positioned at positions away from the disc at the bottom, Since the lower disk is in contact with the lower disk, the upper and lower operations of the lower disk can be regulated even when the disk mounting plate is conveyed into the player body.

Further, in the disc player of the present invention, the slide mechanism is supported by a guide that linearly guides the disc mounting plate toward the player body side, a slide beam moving along the guide, and one end of the slide beam, and is moved forward from the slide beam. And a driving device for reciprocating driving the slide beam.

In this way, by moving the disk mounting plate linearly, the moving space of the disk mounting plate can be made smaller as compared with the conventional method of turning around the trunk portion of the disk mounting plate.

Moreover, in the disc player of this invention, the said guide is provided with the pressing spring for pressing the disc mounting plate conveyed to the player main body side on the said guide.

As a result, the disc mounting plate conveyed to the player main body side is controlled to move up and down by the guide and the pressing spring. Therefore, even if the disc player of the present invention is mounted on an automobile and subjected to vibration on the road surface, the disc mounting plate can be prevented from contacting the disc being played.

Further, in the disc player of the present invention, the elevator mechanism drives the player main body side up and down to align the selected disc, the spindle table of the player main body, and the vertical position of the clamper opposite thereto.

When the magazine is accommodated in large numbers, the height of the magazine is increased. Therefore, lifting the player body rather than lifting the magazine is advantageous to lower the height of the disc player.

By the way, in a disc player, a cover is provided in an opening part so that dust may not enter from the said opening part which is an insertion hole of a magazine, etc. during a performance. However, in the disc player of the present invention, the width can be made smaller than twice the width of the magazine, and in the case where the width is slidably provided in the width direction, the cover having a width capable of covering the opening can be provided. When the opening is opened, the cover pops out of the disc player in the width direction thereof.

In view of the above circumstances, the disc player of the present invention slides in the width direction of the player on the front side of the chassis, and is composed of a cover body and an auxiliary door so that the auxiliary door can be opened and closed with respect to the cover body so that the effective width is variable. The cover is provided.

As a result, the opening can be completely closed by increasing the effective width, and the opening can be completely opened by narrowing the effective width when opening the opening.
